What do you mean I can't decide what is and isn't canon without watching the crossover?! I can and I will.
Barry and Iris got married. Alex and Sara hooked up. Harry and Cisco exchanged some pop-culture references. Somewhere in the multiverse, Snart canonically has a boyfriend. Eobard is somehow alive. This all happened. This is all canon.
Nazibard? Never happened. Stein's death? Never happened. Anything nazi-related in general? Nope. Never happened. There being only 53 Earths instead of infinity of them? Not. Fucking. Canon.
Because I said so.
